Solution:-
The mother is 21 years older than the child.
M = C + 21..............(i)
In 6 years from now the mum will be 5 times as old as the child.
M + 6 = (C + 6) x 5.......(ii)
Hence,
putting in the value of M from equation (i) in equation(ii)
C + 21 + 6 = (C + 6) x 5
C + 27 = 5C + 30
-3 = 4C
C = -3/4
The child is -3/4 years old, that is, it'll be born in 9 months.
Thus.. by mathematical induction....
Right now, the father is on top of the mother...
